Objective: Psoriatic arthritis (PsA) and ankylosing spondylitis (AS) are chronic inflammatory diseases associated with a higher risk of cardiometabolic comorbidities compared to the general population. Individual studies examining mortality in these patients have produced conflicting results. The present study was undertaken to perform a systematic review and meta-analysis to analyze the all-cause and cause-specific mortality in PsA and AS from the available literature. Methods: A comprehensive database search was performed for studies reporting all-cause or cause-specific mortality in patients with PsA and AS compared with the general population. Pooled relative risks (RRs) were calculated using a random-effects model. Results: We included 19 studies (11 of PsA, 7 of AS, 1 of both). In PsA studies, there was no increased mortality compared to the general population (RR 1.12 [95% confidence interval (95% CI) 0.96–1.30]; n = 10 studies). We found a higher all-cause mortality in female (RR 1.19 [95% CI 1.04–1.36]) but not in male (RR 1.02 [95% CI 0.66–1.59]) PsA patients. Cardiovascular-, respiratory-, and infection-specific mortality risks were significantly higher for PsA patients (RR 1.21 [95% CI 1.06–1.38], RR 3.37 [95% CI 1.30–8.72], and RR 2.43 [95% CI 1.01–5.84], respectively), but not cancer-related mortality (RR 1.01 [95% CI 0.91–1.11]). In AS, we found a higher risk of death from all causes (RR 1.64 [95% CI 1.49–1.80]; n = 6 studies) and cardiovascular causes (RR 1.35 [95% CI 1.01–1.81]; n = 3 studies) compared to the general population. All-cause mortality was high in both male (RR 1.56 [95% CI 1.43–1.71]) and female (RR 1.85 [95% CI 1.56–2.18]) AS patients. The included AS studies did not report mortality data for non-cardiovascular causes. Conclusion: This systematic review and meta-analysis showed a significantly increased risk of overall mortality in AS but not PsA. Cardiovascular-specific mortality was higher for both PsA and AS, which emphasizes the importance of early screening and management of cardiovascular risk factors.
